While I have done a world of Handgun and rifle shooting, my knowledge on shotgunning is rather limited. I have done a lot of Waterfowl hunting and always just used the full choke tube. My new shotgun has a 24 inch barrel and three choke tubes. My question is what choke tube would be best for Buckshot and also for slugs? My gun is a new Benelli 3 1/2 inch Camo Sporter. My main use will be home and camping defense and Duck and Goose hunting. Thanks a lot.
